Upgrade your 80" stock big twin motor with the S&S Cycle high compression piston kit, designed for enhanced performance and durability. Crafted for engines requiring a +.020 inch bore, this forged piston kit provides superior strength and reliable operation under demanding conditions. The kit includes a set of pistons, rings, wristpins, and clips, ensuring a comprehensive solution for your engine rebuild or upgrade.
Constructed in the USA, these pistons feature a wrist pin deck height of 1.270 inches, compatible with connecting rods of 7.440 inches in length (standard OEM #24281-74A). When used with earlier connecting rods measuring 7.470 inches (OEM #24281-41A), expect a slight increase in compression ratio by about half a point, which may enhance power output but could also affect clearance. It is essential to carefully check piston-to-cylinder head clearances during installation to ensure optimal performance and prevent potential issues.
Designed for enthusiasts seeking to improve throttle response, acceleration, and overall engine efficiency, the S&S Cycle piston kit is an ideal choice for those restoring or customizing their big twin engines. The forged construction ensures longevity and resistance to wear, making it suitable for both daily riding and high-performance applications. Trust S&S Cycle’s reputation for quality and engineering excellence for your engine upgrade needs.
